Renewable energy is an increasingly important part of our environmental sustainability strategy and our approach to reducing GHG emissions from electricity consumption. For TJX, onsite renewable electricity generation opportunities are limited as we typically do not build or own our stores. Additionally, as a global company, we operate in many different energy and renewables markets, so opportunities for using renewable energy vary greatly from country to country and even within regions. For these reasons, we have regional strategies to support our efforts, and subject matter experts review opportunities, deal structures, and procurement strategies that are currently available in their local marketplaces. They continue to evaluate alternative energy solutions and purchasing opportunities for our facilities, taking into account the economic and operational feasibility of projects.
In 2017, we purchased more than 195 million kilowatt-hours of renewable energy in total, sourced from a variety of technologies. This represents a significant increase in renewable energy consumption compared to 2016. In the U.S. and Canada, our approach to renewable energy includes installing solar panels on select buildings, contracting with utilities for renewables, and purchasing renewable energy credits from national new renewable facilities. Our renewable energy projects and purchases in 2017 enabled us to reduce our Scope 2 market-based GHG inventory by nearly 58,500 metric tons of CO2e, which is estimated to have reduced our aggregate emissions for our 2017 market-based GHG inventory by almost 7.5%.
In the U.S., specific efforts include solar panels installed on the roofs of select stores in New Jersey, Connecticut, New York, Massachusetts, and California and distribution centers in Arizona, Connecticut, and Nevada. We have also designed the roofs on our new distribution centers to accommodate solar panels and have evaluated the potential for solar panel installations at distribution centers and home offices. We believe these efforts position us well to expand our solar projects where it makes sense for the business in the future. In 2017, we were proud to go live with two new solar panel installations on our Arizona distribution centers, including the largest solar panel installation in TJX history.
In Phoenix: Nearly 13,000 solar panels power about 30% of the distribution center’s electricity consumption, netting a carbon savings that is roughly the equivalent of taking more than 285 cars off the road each year. By powering our distribution center, in part, by the sun, we anticipate saving approximately $135,000 per year.
In Tucson: Nearly 4,500 solar panels power about 17% of the distribution center’s electricity consumption, equivalent to the amount of carbon absorbed by about 360 acres of trees and providing a cost savings of about $72,000 per year.
In Canada, in 2017, we purchased renewable energy credits enabling the reduction of close to 75% of our electricity-related emissions and, for the first time, we have purchased carbon offsets that enabled us to completely offset the emissions associated with our scope 3 business travel in Canada. For 80% of our offset purchase, we chose a VCS-certified project known as the Darkwoods Forest Carbon Project, located in southeastern British Columbia, which provides multiple conservation benefits, including protecting over 250,000 acres of forest and ensuring that natural habitats for wildlife are not disrupted.
In Europe, our processing centers in Germany and Poland have incorporated both solar and geothermal technologies.
