Environmental programs and initiatives

The City of London engages residents and businesses with a number of environmental initiatives to help Londoners understand and reduce their environmental impact. 

Environmental programs

Get involved with opportunities to engage with local environmental programs.

Measure your carbon footprint with Project Neutral

The first step you can take is to measure your household's carbon footprint. More than 1,000 London households have already used Project Neutral’s carbon calculator to create a personalized action plan, and start making a positive impact. Discover your carbon footprint in five minutes and better understand your climate impact.

Project Neutral


The City of London's CityGreen program identifies initiatives designed to help Londoners make ‘greener choices’. CityGreen encompasses several departments and divisions within the Corporation and includes such broad topics as sustainability and climate change.

The CityGreen newsletter

CityGreen newsletter (formerly titled “Enviroworks”) provides helpful tips and reminders of the initiatives, projects and programs available to Londoners taking climate action. It is delivered by-monthly through the mail inside your London Hydro bill.

Measuring our impact

In addition to these programs, the City regularly monitors and reports on our environment. 

Community energy use and greenhouse gas emissions

London’s Climate Emergency Action Plan currently has the following greenhouse gas emission reduction goals:

  • 15 percent reduction from 1990 levels by 2020
  • 37 percent reduction by 2030
  • Net-zero emissions by 2050

We measure our community's progress through a Community Energy Use & Greenhouse Gas Emissions Inventory.

Total greenhouse gas emissions in 2019 were 11 percent lower than the 1990 level, which is above the trend line for meeting our 2020 goal.

It is estimated that Londoners spent more than $1.5 billion on energy in 2019. Gasoline is  the largest energy expenditure in London, accounting for 35 percent of city-wide energy costs. Electricity also accounts for about 35 percent of energy costs. Every percentage that Londoners reduce their energy use results in around $13 million staying in London. Through conservation, efficiency, and more local energy production, we can keep more of this money in London. 

Use the Project Neutral carbon calculator to find out your household's greenhouse gas emissions.

The average London household emits almost 11 tonnes of greenhouse gas emissions per year. 

It is estimated that the average household in London, living in a single-family home, spent over $450 every month on energy in 2019. Over half of this, about $240, was spent on gasoline. Electricity accounted for about $100 per month, while natural gas was under $80 per month.

Creeks and Thames River water quality

The Thames River water quality is sampled on a regular basis as part of a monitoring program at 10 locations.  Monitoring is also conducted on a number of creeks in the City of London on a monthly basis.

Water quality in the Thames River has improved significantly since river monitoring was initiated in 1963, but there is still work to do.  Residents can help by making sure that only rain goes down the drain outside, and our catchbasins stay free and clear of chemicals and waste. 

For more information or to request a copy of the Thames River Water Quality Summary, please contact Tony Van Rossum at tvanross@london.ca, or call 519-661-2489 x 5701

Corporate energy conservation and demand management

The 2019-2023 Corporate Energy Conservation and Demand Management Plan is built upon the successful foundation laid by the City’s previous 2014-2018 plan. The 2019-2023 plan helps strengthen corporate energy management practices and gives direction to all service areas on energy management.  The 2019-2023 plan identifies key initiatives, energy standards, achievable measures and commitments towards:

  • Improving energy efficiency within City facilities
  • Reducing greenhouse gas (GHG) emissions and energy consumption in day-to-day operations
  • Extending the lifecycle of the City’s assets where possible
  • Maximizing fiscal resources through direct and indirect energy cost avoidance
  • Monitoring energy consumption and utility usage
  • Demonstrating leadership and awareness within City employees by creating a Culture of Conservation
  • Providing greater budget control towards energy consumption
  • Beginning to control water consumption in City buildings
  • Establishing measures to reach set targets

Ontario Energy and Water Reporting and Benchmarking (EWRB)

2021 EWRB reporting deadline is July 1

For 2021, prescribed, privately owned buildings that are 100,000 square feet or larger are required to report their energy and water use to the Ministry of Energy, Northern Development and Mines (ENDM) by July 1.

Building owners between 50,000-100,000 square feet may also choose to report voluntarily before mandated to in 2023.

Energy and water usage can represent some of the largest operating costs in buildings. Ontario’s Energy and Water Reporting and Benchmarking (EWRB) initiative can help building owners to:

  • Save money by tracking usage
  • Identify energy and water efficiency opportunities
  • Compare your performance to similar buildings

Please ensure you have updated your contact information with ENDM using the Property Owner Contact Update form.

You can use the Portfolio Manager Guide for help using Portfolio Manager.

If you have any additional questions, contact EWRB Support at 1-844-274-0689 or ewrbsupport@ontario.ca.
