London’s climate continues to change. In recent decades, we have experienced warmer, wetter winters and hotter, drier summers than in the 20th century. 

In summer 2022, temperatures exceeded 40C in London and 2025 has been one of the driest and likely to be the warmest on record for the UK. Hotter, drier summers can result in loss of biodiversity with many trees in London having a low tolerance to drought and high temperatures.

The Mayor of London is drafting a London Heat Risk Delivery Plan due to be published Spring 2026.

We’re supporting legal action against Coca-Cola, Nestlé and Danone for their misleading claims about recycling | ClientEarth 
 
ClientEarth is supporting legal action against Coca-Cola, Nestlé, and Danone, accusing them of exaggerating their plastic recycling efforts and misleading the public about their environmental impact. The case reflects rising demand for corporate accountability and could set an important precedent for how green claims are scrutinised and regulated.   
 
The complaint raised states that the recycling statements on plastic water bottles, which are often reinforced by ‘green’ imagery and generic environmental catchphrases, may mislead consumers into viewing single-use bottles as a ‘sustainable’ choice, when this simply isn’t the case. The most sustainable way to consume water is using a refillable bottle and drinking tap water. 

In July 2025, the SBTi launched its first Financial Institutions Net-Zero Standard—a science-based, robust, and credible framework that enables financial institutions to align financial flows with pathways to limit global warming and achieve net-zero emissions by no later than 2050.  

Created in consultation with and tested by financial institutions, the Standard is designed for institutions of all sizes and geographies to use across their lending, asset owner investing, asset manager investing, insurance underwriting, and capital market activities.

Due to the climate emergency, spiralling fuel costs, and customer demand, more businesses are considering owning or leasing cargo bikes. 

Are you considering a new cargo bike, looking to get more out of the one you currently own, or considering expanding your fleet? Do you want to address the Climate Emergency by reducing your carbon emissions, reduce your spiralling fuel costs, or have customers asking if you offer low-emission deliveries? 

If you regularly transport bulky cargo or run a small business that makes frequent light freight deliveries locally, a cargo bike could work for you instead of a car or van. If you’ve tried researching cargo bikes before, you know there is an overwhelming amount of information on the Web, making it difficult to know where to start. This Guide from Cross River Partnership will help inform your decision.

The SME Climate Hub Business Carbon Calculator is a free tool allowing SMEs to calculate their emissions and access recommendations about next steps to being cutting carbon.

The calculator covers Scope 1, 2 and some scope 3 emissions, as listed below:

Scope 1: Direct emissions from the combustion of fuel in assets that a company operates, such as fuel emissions from company-owned cars, diesel generators, gas boilers and air-conditioning leaks.

Scope 2: Indirect emissions from the generation of energy purchased from a utility provider, such as heating, cooling, steam, and electricity.

Scope 3: Upstream emissions from purchased goods and services, capital goods, upstream transport and distribution, and business travel, all of which can be calculated from accounting expenses.

The Greenhouse Gas Protocol (GHG Protocol) is the international standard framework for emissions reporting. Within the GHG Protocol, a full carbon footprint is made up of three levels of emissions sources called ‘scopes’, which are outlined below. The scopes are split out in this way to demonstrate the level of control that an organisation has over the emissions being released.

Scope 1 – direct emissions from gas and other fuels

Includes emissions from activities owned or controlled by your organisation that release emissions into the atmosphere. Examples of scope 1 emissions include emissions from combustion in gas boilers and vehicle emissions from company owned cars.

Scope 2 – indirect emissions from electricity

Includes emissions released into the atmosphere associated with your consumption of purchased electricity, heat, steam and cooling. These are indirect emissions that are a consequence of your organisation’s activities under your operational control, but which occur at sources you do not own or control. The most common example of scope 2 emissions is the electricity purchased from a supplier.

Scope 3 – other indirect emissions

While many companies report on emissions from their direct operations, emissions from a company’s value chain – its scope 3 emissions – often have the biggest GHG impacts. In some cases, scope 3 emissions can account for up to 90% of a business’ total carbon footprint. There are 15 GHG Protocol categories for Scope 3, covering purchased goods and services, waste, transport, as well as investments and energy use throughout the supply chain.

“Building the case for net zero: retrofitting office buildings” stresses the importance of cost-effective and carbon-efficient retrofitting methods. According to the UK Green Building Council (UKGBC), projects without clear retrofit strategies often miss opportunities to reduce energy consumption and streamline the process.

The UKGBC estimates that the offices must cut energy consumption by 59% by 2050 to meet net zero goals, highlighting the crucial role of retrofitting. However, many building owners risk falling behind due to expanding sustainability agendas and minimum energy efficiency standards (MEES). Given that 77% of office buildings have an energy performance certificate (EPC) below grade B, potentially making them unrentable by 2030, the need for proactive retrofitting measures becomes increasingly urgent.

The Better Building Partnership has unveiled the latest edition of its Green Lease Toolkit. Whilst a green lease in simple terms is the legal agreement in a transactional relationship, when seen as part of a wider owner-occupier engagement strategy it can be a powerful tool, unlocking the potential for positive and open dialogue and helping to transform the environmental and social impact of a building.
Originally designed to serve a broad audience, including letting agents, legal professionals, property owners, and investors, the toolkit offers legal provisions covering topics such as the circular economy, waste management, and renewable energy. These clauses can be integrated into leases to enhance the sustainability of commercial properties.

The updated version of the toolkit features the ‘Green Lease Essential’ section, outlining the minimum standards expected for green leases. Given the dynamic nature of sustainability efforts, the Green Lease Toolkit will undergo regular updates to ensure alignment with current industry standards and best practices.
