Why should businesses engage sustainability business leaders as speakers?

Engaging sustainability business leaders brings practical, strategic insight into areas such as ESG integration, climate risk, and responsible growth. According to research, companies that embed sustainability into their core strategy are better positioned for long-term value creation and resilience. In an event setting, a speaker with real-world leadership experience can translate complex policy and environmental challenges into clear, actionable frameworks. For example, a keynote on supply chain decarbonisation can directly inform procurement strategies or internal targets, improving both compliance and performance.

What is Net Zero

Net Zero is defined as the target of achieving a balance between the greenhouse gases that are being emitted into the atmosphere and the greenhouse gases that are being taken out. When the quantity of gas added equals what we take away, net zero is reached.

Source: National Grid

Why is Net Zero Important?

As a society, more needs to be done to combat climate change. Becoming net zero is an important factor in combatting climate change, with the International Panel on Climate Change stressing that “lower greenhouse gas emissions in 2030 lead to a higher chance of keeping peak warming to 1.5°c”.

Source: IPCC

How Can Net Zero Be Achieved?

Transitioning to a net zero society will be one of the biggest challenges that humankind ever faces. To become net zero, we must completely change our way of life, altering everything from how we produce products to how we consume them. One of the most significant contributing factors to climate change is fossil fuels, so the move to renewable energy sources will dramatically reduce carbon emissions.

Source: United Nations

What is Net Zero by 2050?

Net Zero by 2050 is an initiative that has devised a pathway to achieving net zero CO2 emission by the year 2050, encouraging the global energy sector to achieve net zero and minimise their impact on the planet.

“The future will be green, or not at all…”

– Jonathan Porritt

Additionally, 75% of corporate sustainability professionals believe businesses must have eco-conscious strategies, aimed to reduce their carbon footprint. In our latest article, we explore the key plastic swaps businesses can make, that will have the biggest impact on our planet’s future.

What is Plastic Free July?

Plastic Free July takes place from the 1st to the 31st of July 2026. It is a vital initiative, recognised by businesses, governments and individual households across the globe. The annual event has won awards for its impact and is credited for transforming the way we view everyday plastic use. Plastic Free July is a campaign on a mission, to build a future free from waste. Though the event does not have an official theme, there are plenty of important climate issues you can recognise with your event!

In-Person Events → Virtual Events

In-person events are attended by hundreds, if not thousands, of audiences at a time. Such numbers produce tonnes of plastic waste, as single-use coffee cups, utensils, packaging and more are favoured over reusable items, like metal cutlery.

As events and conferences are essential for business growth, what is the alternative? Virtual events.

Online conferences allow attendees to use the home comforts at their fingertips. Easy access to everyday objects like ceramic mugs, and reduced need for physical marketing collateral, all contribute to reducing single-use waste.

The perfect speaker for a virtual sustainability event, Afua Adom can impart top tips for businesses wanting to reduce their plastic use and carbon footprint.

General Waste → Recycling Stations

A simple and sustainable solution for many businesses includes installing recycling stations alongside general waste bins. This allows employees to recycle their plastic waste, rather than contribute to the growing landfill sites struggling with plastic consumption.

Supplying recycling bins is only half the battle; you must also educate your employees. When incorrect items are sent to recycling stations, it can damage equipment, contaminate recyclable materials and impact efficiency.

Teach your employees the correct products to recycle, and reduce your business’ plastic waste.

Traditional Stationary → Re-placeable Cartridges

The stationary cupboard is a staple of every workplace, but it is also home to mountains of plastic waste. Plastic pots, tape dispensers and half-empty pens are commonly discarded after cracks start to show, so why not invest in metal alternatives, like pens with replaceable cartridges?

These swaps last longer than their plastic counterparts and produce significantly less waste.

Alternatively, the humble pencil is a sustainable and often underappreciated option in the office. Pencils can be made from recycled materials and are easily repurposed after use.

Plastic Cutlery → Reusable Utensils

In the workplace, the communal kitchen produces bin bags of plastic waste every day. From single-use plates to plastic cutlery, such items are thrown away in their millions, prioritising ease of use over the planet’s health.

Additionally, plastic items are not cost-effective. By nature, they are produced to be used a small number of times and then thrown away.

Reusable items may require an initial investment, but their longevity leads to long-term savings for businesses.

Supermarket Produce → Green Deliveries

If you want to reduce your workplace’s plastic use, start with the fridge. Green delivery options offer eco-friendly alternatives to plastic-wrapped fruit and milk containers with their quick, cost-effective service.

Though plastic is favoured for its ease of use, glass bottles and paper bags are equally accessible alternatives.

These simple swaps are a great way to continue supplying your employees with tea breaks, while still reducing your business’ plastic consumption.

A smart city is a location in which traditional services are enhanced and made more efficient through digitalisation, ultimately benefiting and improving the lives of its inhabitants. Such ‘smartness’ is not only about increasing digital solutions throughout society, but also about creating a better quality of life for citizens. There is already a collection of cities across the globe that are classed as a ‘Smart City’, which includes: Dubai UAE, GIFT City India, Neom Saudi Arabia, Shanghai China, Amsterdam Netherlands, Brisbane Australia, Copenhagen Denmark and Milton Keynes UK.

How are Smart Cities Sustainable?

Smart cities utilise technology to improve the efficiency of urban operations and services, whilst respecting social, cultural, economic and environmental aspects. Such improvements can span everything from reducing greenhouse gas emissions to upgrading waste disposal facilities and integrating more efficient methods of heating or lighting in buildings. Such aspects are significant contributors to the environmental impact of a community, and so by improving them, smart cities are increasingly more sustainable than normal cities. As smart cities continue to be both created and advanced, it is expected that smart cities of the future will account for 75% of global energy consumption.

Companies like Palmers Orangeries & Conservatories are dedicated to sustainable construction practices. According to their website, the Nottingham-based company plants a tree for every single one they cut down for construction projects, offsetting their impact on the planet. Investing in forest restoration is key for sustainable construction.

What is Sustainable Construction?

Sustainable construction defines an environmentally conscious way of building new houses, office buildings or home extensions. From sourcing sustainable materials to reducing the amount of waste produced from the construction process, there are several practical ways to improve the sector’s impact on the environment.

The sustainability of the construction process is measured by its impact on society, the environment and the economy. Known as the ‘people, planet and profits’ philosophy, this approach equips construction companies and customers with clear, practical guidance to sustainability.

Global experts like Elena Morettini and Alexandra Palt pave the way for environmentally conscious business practices. From renewable energy to ESG, such speakers are regularly booked for corporate events to share their advice with business leaders.

Ways to Ensure Sustainable Construction:

See our five top tips for ensuring sustainable construction!

Watch Your Waste

The production process creates a lot of waste. Hazardous waste, excess materials and onsite litter can pile up and create a big environmental problem. There are several ways to reduce waste on a construction site, including reusing materials and recycling where possible. The biggest change companies can make is to prepare before they step foot on the construction site. Plan which materials you need and how much is required to reduce the potential for unnecessary waste.

Pledge to Replant

Timber is commonly used in construction – however, a tree that takes decades to grow can be cut down within minutes, creating a large problem for the planet’s sustainability. There are several forestry replant organisations doing outstanding work across the world, thanks to donations from construction companies wanting to offset their timber use.

Design for Repurpose

Installation and construction projects are designed to stand the test of time. This is good news for longevity, but once the property owners are ready to sell and move on, these projects can be left empty and unused. To counter this, construction companies should design for repurposing rather than destroy! With mindful construction, a conservatory can be turned into an extended kitchen, or a family home can become an office.

Renew & Recycle

There is a new wave of construction equipment taking the industry by storm: electric. Gone are the days of petrol-powered products; now, zero-emission alternatives are widely available. Additionally, separating waste materials and making a conscious effort to reuse/recycle can drastically improve the impact that construction companies have on the planet.

Invest in Carbon Offsetting

Carbon offsetting initiatives are widely available and are a productive way to care for the planet. Rather than taking primary responsibility for your sustainability, such programmes use donations to invest in global environmental programmes. Calculate your carbon footprint, then invest in carbon offsetting initiatives to balance your impact on the planet.

What is a Circular Economy?

The term ‘circular economy’ was introduced as a means of generating a more sustainable society, and encompasses an evolution of the way in which the world produces and consumes goods. In a circular economy, humans will reuse products and prioritise recycling and remanufacturing – instead of the current society that we live in, in which we ‘take, make and throw away’.

According to the Dame Ellen MacArthur Foundation, “The circular economy is a systems solution framework that tackles global challenges like climate change, biodiversity, loss, waste, and pollution”. It is also based on three principles:

1. Eliminate waste and pollution
2. Circulate products and materials (at their highest rate)
3. Regenerate nature

Products will be redesigned so that they are reusable, durable, repairable and recyclable – which in turn will mean that they are less likely to be thrown away and far more sustainable products are being released into the world around us.

A new and inclusive economic paradigm, a circular economy will minimise pollution and extend the lifecycle of physical and natural assets whilst creating green jobs and keeping resource use within planetary boundaries.

Why Is a Circular Economy Important?

Introducing a circular economy is a crucial factor in slowing down climate change, something that we must as a society address. Natural resource extraction and processing contributes to almost 50% of greenhouse gas emissions, as concluded by the United Nations International Resource Panel, and thus emphasises the need to reduce the impact that material production has on the environment.

A circular economy has the potential to protect the environment from increased climate change, by reducing the levels of greenhouse gases that are released into the atmosphere during material production and preventing high volumes of materials from going into landfill.

A circular economy will help tackle crises on climate, pollution and biodiversity – by reducing habitat loss and waste pollution.

How Does a Circular Economy Work?

The clue is in the name when it comes to the circular economy, the journey of goods and materials is circular. Within a circular economy, materials will be in a continuous flow, from initial production to being reused and recycled, time and time again.

When put into practice, a circular economy implies reducing waste to a minimum – and even when a product does come to the end of its life, the product is reused in some form through recycling – thus the product life cycle is considerably lengthened.

A circular economy is powered by the motto of ‘less raw material, less waste, fewer emissions’.

Source: European Parliament

How Realistic is a Circular Economy?

The concept of a circular economy is incredibly realistic, with some countries having already made steps towards introducing circularity into their way of life. Although the concept may seem aspirational, the concept of circularity has also been adopted by many businesses – ensuring that their products are created with minimal greenhouse gas emissions, and are able to be reused and recycled.

The European Union have also declared that they are aiming to have a fully circular economy by the year 2050, once more emphasising the important reality of a circular economy.

How Can I Play a Part in a Circular Economy?

There are many ways in which you can contribute to the reality of a circular economy. Below are just some of the ways in which this can be achieved:

• Buy products from companies that are committed to a circular economy
• Reuse and recycle products, rather than just throwing them away
• Reduce waste and pollution
• Hire a speaker to learn more about the importance of a circular economy!

The Official Top 10 Speakers on Circular Economy:

Based on verified customer feedback & official data from a market survey conducted across 111 events, The Sustainability Speakers Agency concludes that the following are the 10 best circular economy keynote speakers:

Ellen MacArthur

Dame Ellen MacArthur has enjoyed a successful career, having earned the title of the fastest solo sailor to sail around the world. Having circled the globe, Ellen returned with a new concept of how the world works – including the Earth’s finite resources and how our actions as humans are affecting the world around us. In 2010, Ellen launched the Ellen MacArthur Foundation, a charity organisation committed to accelerating the evolution to a circular economy.

When hired as a circular economy speaker, Ellen emphasises how flawed our current linear system is and what can be done to create a successful circular economy in its place. Having been at one with nature during her daring feats as a sailor, Ellen promotes the importance of reusing materials, eliminating waste and regenerating natural systems.

What Are The Different Types of Renewable Energy?

There are several types of renewable energy, including wind, solar, hydroelectric and bioenergy. Wind power is the largest source of renewable electricity in the UK, generated by onshore and offshore wind farms. Solar energy captures sunlight using panels, converting it into electricity via the photovoltaic effect. Hydroelectric power uses flowing or falling water, including waves and tides, to spin turbines and generate electricity. Bioenergy involves burning organic materials such as plants and food waste. Though it releases carbon dioxide, it is considered renewable as the materials can be regrown, absorbing carbon over time. These sources offer cleaner alternatives to fossil fuels.

Source: National Grid

What Are The Challenges of Renewable Energy?

One of the main challenges of renewable energy in the UK is its inconsistency. Solar and wind power depend on weather, making it difficult to produce a steady supply of electricity year-round. Unlike fossil fuels, which provide constant output, renewables can be unpredictable. To address this, there’s a growing push to develop better energy storage solutions, such as advanced, cost-effective batteries. These would store excess power generated during optimal conditions for later use. However, many renewable technologies are still developing and have yet to fully integrate into society at the same scale and reliability as fossil fuels. The transition remains ongoing.
