Anglo American is one of Chile’s leading copper producers, our major investments in the country’s copper mining industry being Collahuasi, exploiting one of the largest copper deposits in the world, located in the northeast of the country, and the important Los Bronces mine, which we majority-own, around 65 km by road from central Santiago.

Los Bronces came into production over 150 years ago and, because of its proximity to Santiago, the mine and its workforce have had a long association with Chile’s capital city.

As the city has grown – it now numbers more than 7 million people, well over a third of the country’s population – so have the expectations of its residents, including, rightfully, their demand for much more information about how we, as miners, operate, what our impacts are, and how we manage them.

In this constantly evolving world, Anglo American realised early on that, for us, innovation and technology must go hand in hand with sustainability – but also that this is not enough; our licence to continue to operate would also be dependent on how acceptable our activities are in the public domain.

That is why we developed several citizen-participation processes prior to and during the permitting process for our operational-continuity Los Bronces Integrated Project, so we could explain our plans and address community concerns.

 We are doing more than just mitigating emissions from our own operations, and are looking beyond the mine site to improve air quality for our local communities and, most significantly, the city of Santiago. If the air quality improvement initiatives we hope to roll out can minimise Los Bronces’ environmental footprint, while also leading to greater collaboration and trust with the residents of Santiago, then the benefits flowing from improving the region's air quality and the well-being of the population would be innumerable.”

Implementing Los Bronces’ Emissions Compensation Plan

Deteriorating air quality is a significant problem in the city of Santiago – so, in 2022, as part of the Los Bronces Integrated Project, we submitted an Emissions Compensation Plan.

In addition to minimising our own dust emissions from mining and processing operations, we commit to offsetting close to 150% of the project's total emissions per year, versus the mandatory 120%, which would result in a substantial reduction in particulate-matter pollution in the Santiago Metropolitan Region.

Across the Metropolitan Region, residential sources generate more than a third of all air pollution, with wood-fired residential heating being one of the major contributors. 

Moreover, woodburning stoves are a source of PM2.5 – particulate matter that is of significant concern to public health.

So, as part of our Emissions Compensation Plan, we are looking at a set of initiatives, including the replacement, on a large scale, of domestic wood-burners with cleaner, high-tech electric heating.

This is probably one of the most important initiatives to reduce dust emissions in Chile; once executed it would ameliorate the impact of dust emissions, including cardiovascular and respiratory diseases, and lead to a lowering of mortality rates and an estimated reduction in public health costs of around $290 million annually.

It would also help to accelerate the Metropolitan Region’s compliance with regional air-quality standards.

Under the aegis of the plan, we also acquired the 11,000 hectare Los Nogales Sanctuary in the Los Bronces District in early 2024 in order to implement biodiversity conservation initiatives, including conservation, preservation and public use, while also offsetting emissions from Los Bronces.
