Measuring Our Contribution to Sustainable Development
Individually, Copper Alliance® members have been sharing sustainability metrics with the public for years. In 2011, Copper Alliance® members decided to collectively analyze these figures. By doing this on a global scale through ICA, the industry is able to identify areas for benchmarking and collective action. ICA is committed to sharing these figures with the public.
The nine indicators chosen are aligned with the Global Reporting Initiative, which provides a consistent, well-recognized methodology for reporting. Joining this collective effort is voluntary, and in 2017, 24 members participated. These members represent between 40 – 50 percent of global annual copper production.
Amount of World Copper Production Represented by the SD Indicators in 2017
When calculating the indicators, the volume of copper is not double or triple counted as it moves along the manufacturing chain. This means the indicators characterize 10 – 11 million unique copper tonnes per year, representing around 40 percent of the annual world copper used.
Facts & Figures
Many factors, such as the electricity source available at an operation's location, the age of a mine, the ore grade, and processing technology, have an impact on emissions intensity.
Copper Alliance members are taking action to reduce CO2 emissions in their operations. This includes commitments to reach 100 percent renewable energy on site and finding ways to reduce fuel and energy use through innovative technology.
Some members are also working with local utilities to advocate for cleaner energy in the electricity provided.
Energy intensity per tonne of finished copper product was 39 GJ in 2017. Similar to CO2 emissions, some of the factors that affect this figure are in a producer's control and some are not.
Simple energy audits to find opportunities for savings or investing in new energy-efficient equipment, such as the installation of a new concentrator at Freeport MacMoRan's Cerro Verde mine, are a few of the ways Copper Alliance members are improving energy efficiency.
On average in 2017, water was used at least twice before exiting production sites. Copper Alliance members surveyed demonstrate continued positive progress in the amount of water they are able to recycle and reuse during copper production.
For an example of the steps companies are taking to reduce the amount of freshwater they consume, take a look at the new desalinization plant at BHP's Escondida mine.
ICA encourages all of its mining members to use the A Practical Guide to Water Reporting produced by ICMM.
On average, the Copper Alliance members surveyed feed $107 billion per year into the global economy. In 2017, 93 percent of the revenue was redistributed in the form of wages, operating costs, financing, and investing in local community development.
On average, the Copper Alliance members surveyed invest $19 billion every year to improve their contribution to sustainable development. This includes spending on protection of the environment and improving the safety of operations.
The Copper Alliance® members ssurveyed employ nearly 300,000 people on average per year. This does not include the hundreds of thousands of jobs created by the industries using copper. In Chile - where 30% of the world's copper is mined - it is estimated that for each job in a copper mine, 3.7 jobs are created in other sectors of the economy.
Between 2013 and 2014 the Copper Alliance® celebrated a reduction in the injury rate by members surveyed. Significant investment in equipment and training, as well as industry-wide use of the OHSAS 18001 (industrial safety and health protection) certification has driven progress on this indicator.
On average, the Copper Alliance members surveyed invest $19 billion every year to improve their contribution to sustainable development. This includes spending on protection of the environment and improving the safety of operations. BHP's significant investment in sustainable operations at their Escondida mine desalination plant is an example of the scale of these investments.

Measuring Across Three Sectors
Before copper ends up in a finished product, it must go through many stages of processing. The first is mining, where the members who responded produce approximately eight million tonnes of ores and concentrates per year. The second stage, refined production, involves members smelting and refining around nine million tonnes of ores, concentrates and recycled material into cathodes, cakes, and billets annually. The third category is fabrication where members transform around four million tonnes per year of refined copper into semi-fabricates and products such as wire rods and sheets.
The copper industry has a diverse, global footprint.
